It used to be awesome... But over the past 6-8mo or so, I've realized it's NOT sending me push-notifications or Emergency-Alert Audible Notifications any longer, even though from what I can tell in my App Settings- this function appears to be Enabled?! So NOW- this app's great for Reference of Emergency Situations that you ALREADY KNOW happened/are underway... But the major purpose of this App is to ALERT/NOTIFY you of an Emergency Situation taking place because you DON'T already know about it!!

I like the app, but it consumes too much internal storage (830MB) for data. I recognize the usefulness of having data stored locally on the device for an emergency when mobile data networks may be down or overloaded, but the app needs an option to store its data on the SD card.

great information to have, BUT a single high pitched beep from my phone is hardly an alert to an emergency. PLEASE change the alert sound to an option to select the sound and the duration of the sound. That way you'll have my attention when a fire is headed my way! (Do you read these reviews?)
